Add full company search page (#5293)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies.
> - Operators need to find work, documents, agents, projects, comments,
and activity across a company without jumping through separate surfaces.
> - The existing Command-K flow was useful for fast navigation but not
enough for deeper company-wide discovery.
> - Search also needs company-scoped backend contracts, query cost
controls, and indexed document matching so it stays safe as company data
grows.
> - This pull request adds a full company search API and a dedicated
board search page that Command-K can hand off to.
> - The benefit is a single searchable control-plane surface with richer
result context, recents, highlights, and test coverage across server and
UI behavior.

## What Changed

- Added a company-scoped search endpoint/service with query validation,
rate limiting, text matching, fuzzy title matching, and result typing
shared through `@paperclipai/shared`.
- Added idempotent search migrations for document search indexes and
fuzzy matching support.
- Added the full `/companies/:companyKey/search` UI, search result row
components, highlighted snippets, recent searches, and sidebar/Command-K
handoff.
- Added Storybook coverage for search surfaces and Vitest coverage for
server search behavior, rate limiting, route generation, Command-K
behavior, and the search page.
- Addressed Greptile findings by renaming the no-match SQL helper,
applying search pagination after cross-type merge sorting, and
lazy-initializing the default search service so unrelated route-test
mocks do not need to know about it.
- Merged current `public-gh/master` and renumbered the search migrations
behind upstream `0078_white_darwin`: search indexes are now
`0079_company_search_document_indexes` and fuzzy matching is
`0080_company_search_fuzzystrmatch`.

## Verification

- `git fetch public-gh master`
- `git diff --check public-gh/master...HEAD`
- `git diff --name-only public-gh/master...HEAD | rg '^pnpm-lock\.yaml$'
|| true` produced no output before opening the PR.
- `pnpm run preflight:workspace-links && pnpm exec vitest run
server/src/__tests__/company-search-service.test.ts
server/src/__tests__/company-search-rate-limit-routes.test.ts
ui/src/pages/Search.test.tsx ui/src/components/CommandPalette.test.tsx
ui/src/lib/company-routes.test.ts` passed: 5 files, 25 tests.
- `pnpm --filter @paperclipai/shared typecheck && pnpm --filter
@paperclipai/db typecheck && pnpm --filter @paperclipai/server typecheck
&& pnpm --filter @paperclipai/ui typecheck` passed.
- `pnpm exec vitest run
server/src/__tests__/company-search-service.test.ts
server/src/__tests__/company-search-rate-limit-routes.test.ts && pnpm
--filter @paperclipai/server typecheck` passed after Greptile pagination
fixes.
- `pnpm exec vitest run
server/src/__tests__/issue-agent-mutation-ownership-routes.test.ts
server/src/__tests__/company-search-rate-limit-routes.test.ts
server/src/__tests__/company-search-service.test.ts && pnpm --filter
@paperclipai/server typecheck` passed after the CI mock fix.
- After resolving the migration conflict with current
`public-gh/master`: `pnpm --filter @paperclipai/db typecheck && pnpm
exec vitest run server/src/__tests__/company-search-service.test.ts
server/src/__tests__/company-search-rate-limit-routes.test.ts && pnpm
--filter @paperclipai/server typecheck` passed.
- DB migration numbering check passed as part of `@paperclipai/db`
typecheck.
- UI states are covered by the added Storybook stories in
`ui/storybook/stories/search.stories.tsx`.
- GitHub reports the PR merge state as `CLEAN` on head `18e54fa8`.
- GitHub PR checks are green on head `18e54fa8`: policy, verify,
serialized server shards 1/4 through 4/4, e2e, canary dry run, Snyk, and
Greptile Review.

## Risks

- Search ranking and snippets are new user-facing behavior, so reviewers
should check whether result ordering feels right on real company data.
- Search touches broad company data, so company scoping and query
cost/rate-limit behavior should be reviewed carefully.
- The migrations add search indexes/extensions; they are idempotent with
`IF NOT EXISTS` for users who may have applied an earlier branch
migration number.

> ROADMAP.md checked. This PR adds a focused board search surface and
does not duplicate an open roadmap item.

## Model Used

- OpenAI Codex, GPT-5 coding agent, tool-enabled shell/git/GitHub CLI
session with medium reasoning effort. Existing branch commits were
produced across prior agent sessions; this packaging pass verified,
opened the PR, addressed Greptile findings, resolved migration conflicts
after upstream PRs landed, and got PR checks green.
